today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

Hierarchical-based protocols are some of the most popular routing schemes used in wireless sensor networks due to their favorable, energy-saving properties. However, when it comes to large-scale wireless sensor network applications, these algorithms suffer from an increase in computational complexity and latency. In this paper, a parallel algorithm for the hierarchical-based protocol has been d...

Energy Conservation and prolonging the life of Wireless Sensor Network is one of the major issues in the wireless sensor network as sensor nodes are highly energy constrained devices. Many routing protocols have been proposed for sensor network, especially cluster based routing protocols. Cluster based routing protocols are best known for its energy efficiency, network stability and for increas...

BACKGROUND Wireless sensor networks (WSNs) are a promising area for both researchers and industry because of their various applications The sensor node expends the majority of its energy on communication with other nodes. Therefore, the routing protocol plays an important role in delivering network data while minimizing energy consumption as much as possible. The chain-based routing approach is...

In this paper, we study how energy-efficient routing at the network layer can be coordinated with sleep scheduling at the link layer to increase networkwide energy efficiency in wireless ad hoc networks. We identify a trade-off between the reduced transmit power at senders with multi-receiver diversity and the increased receive power at forwarders with coordinated sleep scheduling. Moreover, we...
